It depends on the company. Most places give you the housing allowance as cash on top of your regular salary for you to use as you see fit. So, if you have a housing allowance of QR10,000 and you find a place for QR8,000 the remaining 2000 is yours. A few employers, however, will pay the housing allowance directly to the landlord. So, in the above example, they would only pay your QR8000 rent and you would not see the remaining 2000. Check with your employer to find out how they do it.
